hmm... I'll wait until this next Hulk movie comes out first.. a She-Hulk would have to be handled very carefully.. Ideally, she hulk would not be CGI, but a real person, just green. At the same time, she'd have to be muscular like a female bodybuilder, but not ultra-bulky-- still sexy. At the risk of disaster, the ideal physical type would be a female wrestler from WWE-- but-- of course, the person needs to be able to "ACT" and emote.. on the flip side, the Jennifer Walters would have to be a very normal size, if not petite, woman. I don't think it would work to have the same actress play both roles.
